In this edition, we bring you key highlights from the Ethereum ecosystem, including updates on the upcoming Pectra (Prague + Electra) upgrade, insights from the latest All Core Devs Consensus Call, and details on recent implementers’ and breakout meetings. For those new to this series, don’t worry—you can catch up with our previous newsletter here.

Other highlights include exciting news about Ethereum Improvement Proposals (EIPs) in progress, updates on the Public Goods Funding, and upcoming events. Stay tuned for more updates as we continue our mission to empower Ethereum through education, community building, and innovation.

Pectra (Prague+Electra) Upgrade

Consensus (ACDC) #149, (January 23, 2025)

Pectra Interop #21 (January 20, 2025)

  • Move forward with Pectra devnet 6, incorporating a new genesis file and validator set increase to 50,000–100,000.
  • Mario will release updates with EIP-7702 changes and fixes.
  • Client teams to review and comment on PRs as needed.
  • Notes by EthCatHerders, Fellowship of EthMagicians. No recording is available.

Breakout & Implementers’ Meeting

EOF Implementers Call #65 (Jan 22nd, 2025)

JSON-RPC Standardization Breakout (Jan 20, 2024)

This is a new breakout room meeting initiated as a result of discussion to be continued from the last ACDE.

  • The discussion focused on broader goals and stakeholder involvement, emphasizing the need to refine internal processes before involving external stakeholders like wallets and RPC providers.
  • Suggestions included using the group to address consistency issues and align new feature proposals with broader stakeholder needs.
  • Key action items were identified:
    • incorporating eth_fillTransaction `into the execution spec, refining and documenting new methods, ensuring RPC compatibility through rigorous testing, and improving specification documentation for better usability.
  • As next step, devs decided to continue async discussions on eth_fillTransaction and RPC compatibility tests on Discord.
  • Future discussions will prioritize error handling and establishing processes for integrating new features and methods.
  • The next meeting will be scheduled in the next two weeks.
  • Recording & Notes by EthCatHerders

EIPIP Metting #112 (January 15, 2025)

  • Stagnant Tag Discussion: A few suggestions to address issues with the "Stagnant" tag for Core EIPs under active consideration. Will bediscussed further in the next meeting.
  • EIP Reviewers: Proposal to introduce formal EIP Reviewer roles approved. Details to be finalized in the Editors' Workshop.
  • Editors' Workshop Announcement: Workshop planned for onboarding and discussions.
  • Proposal Builder Tool:
    • Get the .md file to document a proposal using this tool. Demo shared, tool deemed useful for new authors.
    • Requested adding the tool link to eips.ethereum.org.

EVM Resource Pricing Breakout #1 (January 15, 2025)

The Gas Repricing Working Group meeting is a new breakout focused on three key agenda items: benchmarking efforts, short-term pricing changes, and research for medium-term updates.

Presentations included an overview of the Nethermind gas-benchmarks tool by Marek, showcasing its use in identifying bottlenecks, and Jacek’s Gas Cost Estimator tool, which proposed updated gas cost schedules tested across seven EL clients.

Discussions addressed strategies for short-term adjustments, such as single and multi-block warming to improve efficiency, and medium-term considerations for hardforks like Fusaka and Amsterdam. Concerns around backward compatibility were highlighted, with suggestions to leverage EOF mechanisms for versioning and restrict gas schedule changes to EOF contracts.

  • Benchmarking Efforts:
    • Tools presented for analyzing gas costs and addressing bottlenecks in existing schedules.
    • Proposals to refine gas pricing schedules for greater efficiency.
  • Short-Term Pricing Changes:
    • Adjustments to precompile gas costs due to benchmarking insights revealing they are underpriced.
    • Ideas like single and multi-block warming were discussed, with efficiency gains estimated at 5-6% for single block and ~15% for multi-block.
  • Medium-Term Strategy:
    • Addressed strategies for future hardforks like Fusaka & Amsterdam.
    • Backward compatibility concerns raised about repricing, with suggestions to restrict changes to EOF contracts.
    • Agreement that increasing gas prices historically caused breakages, while reducing prices carries lower risk.
  • Backward Compatibility:
    • Suggested leveraging EOF mechanisms for versioning to mitigate issues.
    • Discussions on feasibility of automating checks to detect potential contract breakages.
  • Future Considerations:
    • Incentivizing fair contract usage without disadvantaging smaller contracts.
    • Exploring zk-proof pricing adjustments (e.g., 10x keccak costs).
    • Dcrapis proposed a session on EVM memory pricing, potentially to be covered in a future call if time doesn’t permit.

Action Items

  • Draft EIPs for short-term pricing changes.
  • Continue benchmarking efforts to refine gas cost schedules.
  • Explore applying new gas schedules only to EOF contracts to preserve legacy compatibility.
  • Schedule EVM memory pricing presentation for the next call.
